Nuevo León (Spanish for "New León", after the former kingdom in Spain) is a state located in north-eastern Mexico. It borders the Mexican states of Tamaulipas to the north and east, Zacatecas and San Luis Potosí to the south, and Coahuila to the west. To the north, Nuevo León also shares a 15 km stretch of borderline with Texas, (USA).

It was originally founded by Alberto del Canto, although frequent raids by Chichimecas, the natives of the north, prevented the establishment of almost any permanent settlements. Subsequent to the failure of del Canto to populate Nuevo Leon, Luis Carvajal y de la Cueva, at the head of Portuguese and Spanish settlers, requested permision from the Spanish King to attempt to repopulate the area.

The capital city of Nuevo León is Monterrey.
